Q515. Are dehydration units that are used to dehydrate natural gas extracted from underground storage included within the definition of underground natural gas storage facility?

A515. The sources required to report under the underground storage source category are listed in 40 CFR 98.232(f). The amendments on May 14, 2024, added requirements to report emissions from dehydration units beginning in RY 2025. Reporting from this source type is not required for reporting years prior to RY 2025.
